The Bose will be better then the Logitech. Id stay away from Logitech if you want real sound. Logitech speakers are just loud, which is why some people think they are good. When really they have nothing against real speakers for the same price. What do you want a sub for?

Absolutely love them and have never used anything that is remotely even close in quality. The specific reason I like them is that they're very flexible whether gaming or Mozart...they sound great and have very nice high's and strong mid's. Almost feel like a set of Bose...for a small speaker system they fill the room with sound quite well.

You can routinely find a good used set for a hundred or under on E-bay...that might be an option. I have an extra set of the original version I plan on putting up there soon.

I built a sound system that cost about $500 and after listening to it and comparing it to the Klipsch Pro media 2.1 I took the Polk speakers back and bought klipsch synergy b-20 speakers. You might be able to fine some used
